Dear Alex, yes I read the README files.
Once more, the A[M/F].dat can be open with a VOXEL as it is. Perhaps theres some inversion in the coordinates but nothing that any matrix handling code can work out.
What you need to do is to define the correct material for each organ. This is indeed obtained simple scripting and you are not bound to Fortran. As a matter of fact I approached similar problem both in bash and python. The technical knowledge required is not dramatic.

There are very few simulation cases where one doesn’t need to get the hand a bit dirty with coding. The task can be also approached manually and will not require you more than a couple of hours for the material definition (definition of the compounds and the assignment of the organ to the correct material). It’s outside of the scopes of the list to solve the problem for you but we are more than happy to help you debugging your simulation in case you get a first draft of the input file.

Best,
Vittorio

Next step is to define for you the material/composition of each organ id. Correspondence between ID and density can be found in A[M/F]_organs .dat, Material composition can be found in the A[M/F]_media.dat file.

As the organ and media definition are in a pseudo-nicely-formatted ASCII, one can obtain a decent input file with a few lines of python or another scripting language in about an hour or word or less. Alternatively the same results can be obtained in a few hours more by building the materials in the good ol’ way.
